Need advise (girls only would be nice)?

Me and my girlfriend ran into alitle jiffy while on the phone tonight. We rarely ever fight but this one took the cake as probably the bigest one we had. As for right now I feel like uder horse ****. She really loves it when I randomly txt her early in the moring befor she wakes up. All I want is for her to feel better (I don't even care if I don't) but what is something I can tell her that would either 1: make her heart melt, or 2: reasure her how much I love her and how no fight will ever bring me away from her. PLEASE any advise will help. Heart felt thanks.
